An Advertiser has 48 hours to respond to a booking request before it is automatically cancelled. This is to ensure that the Traveller doesn't spend a long time waiting to find out if they can secure the hire.
In turn, once a booking request has been accepted the traveller has 72 hours to confirm it by making a payment, otherwise it is automatically cancelled. This is to ensure that advertisers don't miss out on bookings and income.
We recommend sending out a few requests at a time to increase your chances of one getting accepted.
